为了解决本公司硫铵车间液氨储罐液位连锁控制液位不准、不稳定问题，通过对差压式液位变送器、磁翻板液位计、ELL型外测液位计三种不同原理的液位计现场实际应用情况的对比，最后采用了ELL外测液位计测量液氨储罐液位的方法，有效解决了液氨储罐液位测量不准确、不稳定的问题，最终实现了液氨储罐液位的连锁控制，为企业提高了生产效率和安全管理水平。%In the company,the ammonium sulfate of plant,order to solve the level Liquid ammonia tank level interlock control inaccurate and instability,contrast to differential pressure level transmitter, magnetic level gauge, ELL-type liquidometer, principle three different liquidometer field application conditions. Finally, the ELL-type of measured outside liquidometer Liquid ammonia tank levels measurement method. Effective solution to the Liquid ammonia tank levels measurement is not accurate, the problem of instability. Finally achieved chain of Liquid ammonia tank levels interlock control. For enterprises to improve production efficiency and safety management.
